VALVE MECHANISM.

hpp licatienlfile d April 25, 1913. Serial No. 763,668.

To all whom it may mm Be it known that I, H RY Gites, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new useful Improvements in 1V l ve Mechanism, of which I do declare the following to be a full, clear, and enact description.

The present invention has for its object to provide an improvedlconstruetion of valve, more particularly'designed for radiators of hot water systems and the invention consists in'the features of novelty hereinafter described, illustrated in the accompanying drawing and particularly pointed out in the claims at the ofthis specification. i Figure invention. F ig. 2 is a view in horizontal section on the l ne 22 of lllg 1. F1g, 3 1s a view in vert cal section (parts belng shown in elevation) on lineES-Ei of Fig, 1.

valve fbeing tr'uly cylindric, ,whilethe top of the valve is preferably slightly crowned.

Through the body of the valve 1 L formed an opening 15 adaptedto register with the, passage 12in the valve In the top; of the valve 14 are formed the holes 16 and; 17, the central hole 17se rving to receive,-

a squared portion 18 of the valve stem 'that passes through the upper portion of the casing. The lower end of the valve stem is screw-threaded, as at 20, to receive the retaining nut 21, and preferably a washer 22 is interposed between the nut"21 andthe under side of the top of the valve 14:. The

squared portion 18 of the valvestem also Pa through c respond n ly u r opening 25 the stopplate 26. This stop Specification of Letters Patent.

plate 26 is provided with the lugs 27 adapted to pass through the openings 16 in the top of the valve 14, so that when the stop plate 26 is rotated by the turning of the valve stem, a corresponding rotation will be imparted to the valve 14L The stop plate 26 occupies a'position 'within the casing immediately abovethe top of the valve 1 1 and this stop plate is provided with a stop arm '29 that'is' adapted to contact with the shoulders 30 formed in the valve casing, so as to limit the extent of rotation of the valve 14. When the stop arm 29' of the stopplate is against one of the shoulders 30, the valve will be in completely open position, as illustrated'in Fig. 1, and when the stop arm 29 is brought into contact with the opposite shoulder 30, the valveill will be in completely closed position' "Above the opening 32in the top of the valve casing, through'which opening the .valve stem passes, is formed an annular shoulder 33 forming a valve seat against which bears a' supplemental valve 34 carried by the valve stem. Preferably this supplementalvalve consists of a fiber washer 35 against which bears an annular flange or shoulder ,36 that is integral with or rigidly secured to the valve stem. This supplemental valve sets within a stuffing box 37 that is formed in the upper part of the easing, and in this stuffing box and around the valve stem suitable packing 38 will be placed, this packing being held in position by an annular gland 39through which the valve stem passes. A collar 40 sets over the gland 39 and the lower portion ofthis collar is screw;threaded to engage the correspondingly 'e' y hre ded Wel offthe stu e' box 37. That part of the valve stem that passes through the stufiingbox gland 39 and the collar {10 is cylindrical and to the upper ar the w s em i miser b y e nected a hand wheel by which the valve Fr thef r e'Ome d'es ript on' t be seen that when the valve 14 is in the position illustrated in Fig. 1 ofthe drawings, water may pass freely through the valve casing.

When, however, it is desired to out 01f the flow of water, the valve will be turned by manipulating the hand wheel 45, until the valve more or less closesthe port 12 of the ea in It will be observed that the opening 15 in the valve 1% is some distance above the bottom of the valve, so that sufiicient metal is left to give rigidity to the valve and guard against danger of its being distorted. Inasmuch as the valve is stamped frorn sheet metal, it can be formed truly cylindric and the necessity of machining the surface of the 5 scrlbed comprislng a casing formed with valve is avoided.

My present construction of valve mechanism is much more effective than that familiar type of radiator valve mechanism in which the valve and valve stem are formed integral. One serious objection to forming the valve and valve stem integral is that it is extremely difficult to machine the outer surface of the valve, so that it shall be both truly cylindric and in exact alinement with the valve stem. Another marked advantage of my present invention is the employment of the supplemental valve on the valve stem and arranged to cooperate with an annular seat or shoulder at the inner end of the stulfing box. By this arrangement, the stufling box can be repaoked without danger of leakage, it being simply necessary during such repacking operation to tightly force the supplemental valve against the annular shoulder or valve seat 33. A further advantage of my present construction is that the supplemental valve 34 arranged, as it is above the shoulder 32 of the valve casing, will prevent any forcible depression of the valve that might tend to disarrange its location within the casing. Valves of this character are frequently located adjacent the fioor, and it will therefore be perceived that it is a decided advantage to guard against any danger of the disarrangement of the valve within the casing incident to accidental pressure of the foot upon the hand-wheel at the outer end of the valve stem.

The precise details of construction can be varied without departure from the spirit of the invention and features of the invention may be employed without its adoption as an entirety.

Having thus described my invention, what i claim as new and desire to secure by Letters Patent is 1. Valve mechanism of the character described, comprising a casing formed with channels arranged at an angle to each other for the passage of fluid through the casing, the interior of the casing having a truly cylindrical chamber, an inverted cup-shaped valve formed from a single piece of thin sheet metal having a truly cylindrical body to engage and snugly fit within said casing, one side of said valve being formed with an opening to register with a channel of the casing and the top of said valve being formed with a hole, a valve stem passing through the hole in the top of the valve, a

plate arranged at the top of said valve and within the upper part of the valve casing and being interlocked with said valve stem and said valve, means for preventing the downward pressure of said valve stem upon the top of said valve, and means for limiting the rotation of said valve stem.

2. Valve mechanism of the character dechannels for the passage of liquid, said casing having a cylindrical chamber with which said passages connect, an inverted, cylindrical, cup-shaped valve formed of thin sheet metal located 'within and fitting snugly against the wall of said cylindrical chamber, said valve having an opening in its side to register with one of said passage Ways and having a perforated top, said casing having a wide bottom opening to admit the Valve and the top of said casing having a contracted opening above the top of said valve, a valve stem passing through said contracted opening of the casing and engaging the perforated top of said valve, and means for preventing the downward pressure of said valve stem upon the top of said valve comprising an annular part secured to said valve stem of greater diameter than and located above the contracted opening of the casing through which the valve stem passes. 95
